Biff -
I had same symthoms last month (that is my bugeye did, not me
personally). I checked all the same stuff you have. No improvement.
Per the advise of listers, I added several gallons of new gasoline -
immediate improvement. Either some "bad" gas or a little moisture in
tank. Try it - sometimes the simple solutions do work.
